Early people found fire in natural forms, and it became a central part of life long before they learned how to make it themselves. We know that many of today's forest fires are set by lightning. These fires were just as common in the days of early people. There were also fires that came from the hot lava of volcanoes. And there were fires started by sparks from stones crashing together. What people saw taught them how to use fire. But when they first used fire, they had to carry it with them from place to place. They did not know how to make it themselves. Certain members of the tribe became "keepers of the fire". In fact, fire became part of the religion of many tribes. Because it was so valuable, fire was worshiped by the tribes.
